title: A Mysterious Boy With a Horn and Robin's Deduction!
Robin informs the Straw Hats about the memories erased from them. Meanwhile, Nami, who left the ship, arrives on a nearby island.
A newspaper is dropped from a seagull, and all the residents in the village fight each other over the newspaper. Nami then meets the boy who erased the Straw Hats' memories.
He tells her to ride around the island. Robin then explains what happened the night they lost their memories.
They deduce that only those who fell asleep lost their memories, and that the child stole their memories by playing the low-pitched horn.
